Ionizable lipid review

Web6 jan. 2024 · Cationic and ionizable cationic lipids are broadly applied as auxiliary agents, but their use is associated with adverse effects. If these excipients are rapidly degraded to endogenously occurring metabolites such as amino acids and fatty acids, their toxic potential can be minimized. WebIonizable Lipid. Ionizable lipids are protonated at low pH, which makes them positively charged, but they remain neutral at physiological pH. The pH-sensitivity of ionizable lipids is beneficial for mRNA delivery in vivo, because neutral lipids have less interactions with the anionic membranes of blood cells and, thus, improve the ...
